%description
R interface for 'H2O', the scalable open source machine learning platform
that offers parallelized implementations of many supervised and
unsupervised machine learning algorithms such as Generalized Linear Models
(GLM), Gradient Boosting Machines (including XGBoost), Random Forests,
Deep Neural Networks (Deep Learning), Stacked Ensembles, Naive Bayes,
Generalized Additive Models (GAM), ANOVA GLM, Cox Proportional Hazards,
K-Means, PCA, ModelSelection, Word2Vec, as well as a fully automatic
machine learning algorithm (H2O AutoML).
